What the walkthrough won't tell you
If you're under contract on a house in Republic right now, you've probably already walked the lot twice, run the faucets, flushed the toilets, and told yourself the plumbing seems fine. That's normal. It's also not enough. Republic has grown fast over the last two decades, which means you'll find everything from 1970s ranch houses near the older parts of town to brand-new builds out toward the edges of the subdivisions off Highway 174 and around Hartville Road. Each era of construction brings its own plumbing habits, and some of those habits don't show up until a few years after move-in.
Older homes in Republic were often built with galvanized steel supply lines or early copper, and some still carry the original cast iron drain stacks. Neither fails all at once. They narrow, they rust from the inside, they weep slowly behind a wall. A seller who has lived in the house for twenty years may genuinely not know there's a problem, because low water pressure crept in gradually and they just adjusted.
Why southwest Missouri soil and weather matter here
Greene County sits on clay-heavy soil that swells when it's wet and shrinks hard during dry stretches. Republic gets its share of both, heavy spring rain followed by the kind of late-summer dry spell that cracks the ground visibly in yards and fields. That cycle moves foundations, even slightly, and shifting foundations stress the pipes running through and under them. A slab leak that wouldn't happen in a region with stable soil is a realistic concern in a house built directly on a slab here, especially ones put up before builders started accounting for this kind of ground movement.
Winter adds its own pressure. We don't get the brutal deep freezes of further north, but Republic does get sharp cold snaps, sometimes a hard freeze after a mild stretch, and that combination catches people off guard. Pipes running through unheated crawl spaces or along exterior walls without much insulation are the ones that split. If the house you're buying has a crawl space, which a lot of homes in this area do, ask when it was last opened up and looked at.

What you can actually check yourself before closing
Run every fixture at once if you can, a shower, a sink, and a toilet flushing simultaneously, and see if pressure drops noticeably anywhere. Look under every sink for water stains, swollen wood, or a faint mineral crust around fittings, that's old evidence of a slow drip someone wiped up and never fixed properly. Check the water heater's manufacture date on its label. In this area, a tank past twelve or fifteen years is living on borrowed time.
If there's a crawl space and you're comfortable with a flashlight and getting a little dirty, look for standing water, sagging insulation, or pipes with visible corrosion. Look at the main shutoff valve too. If it's stiff, corroded, or clearly original to a decades-old house, that's worth a note even if it's not an emergency.
Where it stops being a homeowner job
Anything below the slab or inside a wall is not something you can evaluate with a flashlight and good intentions. A sewer scope, a camera run through the main line, is the one inspection item that routinely gets skipped and routinely causes the most expensive surprises. Tree roots are common in older Republic neighborhoods with mature trees, and roots find their way into clay or early PVC lines through joints that have shifted even slightly. A scope costs a fraction of what a collapsed line costs to replace.
A full plumbing inspection before closing, separate from the general home inspection, is worth asking for directly, especially on any house built before the 1990s or any house with a crawl space you can't fully see into. General inspectors check that water runs and drains. They're not always looking at pipe material, water pressure consistency, or the condition of a water heater with the same depth a plumber would. For a purchase this size, that gap is worth closing before you sign anything, not after.
